Abstract

The invention discloses a saw band feeding automatic speed changing sawing machine which comprises a saw frame, a lifting device used for controlling lifting of a saw band, a guide assembly arranged on the saw frame and the saw band fixed to the guide assembly. The guide assembly comprises a clamping device used for fixing the saw band and a speed adjusting valve used for controlling the lifting speed of the lifting device. The speed regulating valve communicates with the lifting device through an oil path. According to the saw band feeding automatic speed changing sawing machine, automatic speed adjusting of saw band feeding is achieved, the response speed is high, and speed changing is accurate; the service life of the saw band is prolonged.

Description

technical field [0001] The invention relates to a sawing machine, in particular to a sawing machine with automatic speed change of saw band feeding. Background technique [0002] During the sawing process of the traditional sawing machine, when the saw band cuts and feeds, its feed rate remains unchanged, but when the sawing section is circular or other sawing rates will be appropriately changed, due to its feed rate No change, when the feed rate is too large, the saw band will bear too much sawing pressure, which will easily cause saw band fatigue, but the service life of the saw band will be shortened. When the feed rate is too small, the sawing pressure will be small and the sawing efficiency will be low . However, the existing sawing machines control the feed speed of the saw band through a speed regulating valve, but this method has a single control mode and cannot achieve the purpose of automatic speed regulation; The speed change by current feedback has problems suc...
